“Our research predicts that aridification would emerge over about 20-30 percent of the world’s land surface by the time the global mean temperature change reaches 2ºC,” said Manoj Joshi, the lead researcher of the study.

“But two-thirds of the affected regions could avoid significant aridification if warming is limited to 1.5ºC (34.7 degrees Fahrenheit).”

The study goes on to point out that reducing greenhouse gas emissions will keep global warming under the 2 degree threshold and reduce the likelihood of aridification.
